Answer to Problem 1CQ

The leptons are lighter than the protons and neutrons.

Explanation of Solution

The particles were grouped into three primary groups: leptons, mesons, and baryons. The leptons are the lightest particles and include electrons, positrons, and the neutrinos involved in beta decay.

Neutrons and protons occupy more volume than electron. Electron is a point particle and an elementary particle. Neutrons and the protons are baryons and they both will make some quarks, another quantum, another point particle.

Leptons are mostly lighter particles and they include the almost massless neutrinos, the electron and the muon. The heaviest of this group is the tauon and is almost twice the mass of the proton still.

Conclusion:

Therefore, leptons are the lighter particles than the protons and neutrons.
